To all whom it may concern:

Be it known that I, JOHN FREDERICK MA KOWSKI, a citizen of the United States, re-

siding in the city and county of San Fra-n cisco, State of California, have invented a new andusefullmprovement in Sand-Moving Machines, of which the following is a specification.

My invention relates to sand moving machines, and has for its object to provide in machines of the character specified new and IIIIPI'OVGd means for digging away sand acwardly inclined box to a point over'the cars,.

and for dropping the sand so lifted into the cars.

It also'consists in the novel parts, combinations, and arrangements set forth in the following description, particularly pointed out in the claims, and illustrated in the accomlpanying drawing. 1

T e drawing shows a side elevation of my machine.

Referring to the drawing, my machine consists of a frame 1, mounted on trucks 2, and a rail 3, which runs parallel with the slope to be attacked, whereby the machine may be shifted along the line of the S10 e back and forth, and made to approach t e gradually receding face of the hill .by throwing the. track nearer the same. 7

A motor 4, of suitable characteris located in the frame, and is operatively connected with the main shaft 5, on which a sprocket .6, is-located.

Fixed to the frame and extending to near the level of the ground is a box 7, which rises to a point on the frame above the cars to be loaded, and has an extension 8, outwardly therefrom and over the cars, provided with an open bottom 9, through which the sand falls into the cars.

An endless chain 10, is provided with- 'of the sprocket 14,. consistin within the scope allow it to fall into the cars. The chain passes over the sprocket 6, and overidle d, 15. Sprocket 13, is

sprockets 13, 14, an plvoted in a guide block 16, and has a counterhalancing weight 17, which automatically takes up thevariations of slack in the chain 10, which arise in the operation of the machlne. Sprocket 14, is pivoted at theend of a boom 18., which is hinged to box 7, near its lowest extremity, and which may be moved about said hinge in a vertical plane.

Sprocket 15, is located at :a point near the lowest extremity of the box, and acts so as to guide the chain into the box.

An auxiliary digging device 19, is located at the far end of the boom on the shaft of blades adapted to be rotated by said loosen the sand in the vicinity of sprocket 14, so the scoops canreadily draw it to the box 7.; The device 19, saves the labor of several shovelers, and helps to bring the sand to the desired position by causing rapid caving as the supporting parts of the sandhill .are drawn away. The chain driven by sprocket 6, carries the scoops over sprocket 13, and pulls the sand along from the end of the boom 18, to

the lower opening of the box 7. There it is drawn into the box 7, 'and pushed along the bottom'thereof to the extension 8, .Where it drops into; the car 20.

s aft, and to,

The arrangement'for drawing the sand I into a box and pushing it upward b plates or scoops, gives greater flexibility t an can be obtained by buckets, a smaller motor be ing available for operating the machine, and smaller plates or scoops bein usable. A switch track 21, parallels trac 3, and the cars are run thereon.

Having described my invention what I claim as new and desire to secure by Letters Patent of the United States, modifications of the claims being expressly reserved is:

1. In a device of the character specified a frame, a box extending diagonally from a' point near the ground level to a point over the cars to be loaded, having an opening above said cars, a boom hinged to the lower end of said box movable in a vertical plane,

a boom sprocket located near the outer exv tremity of said boom, a box sprocket located near the bottom, of the box, a driving sprocket, a guideblock having a sprocket and a counterbalancing weight, other sprockets on said frame, and an endless chain passing around said sprockets provided with plates of a size adapted to pass through the box 2. In an excavator, a car, a supporting frame extending above the car, an inclined chute extending across the car, an endless carrier having flights extending into the chute, a driving wheel on said frame at the upper end of said chute around which the carrier passes, a pivoted link at the bot tom of said chute, a wheel at the bottom of the chute, afwheel carried by the link, another wheel at the top of the frame, said carrier passing around all of said wheels, a

counter-weight connected with the upper
